A new method of characterizing sharp interfaces is presented. The method utilizes the structural modification of the interface caused by thermal-neutron-induced recoil. Dual neutron activations, coupled with chemical etching, are used to correlate the initial and the modified material distributions across the interface. The nuclear and the radiochemical aspects of the method are tested For samples...
We live in a dusty Universe! Dust is not only found in our solar system among the planets but is found in a wide variety of objects throughout the Universe, mainly in those regions between the stars known as interstellar clouds. Interstellar dust particles, which consist of cores of silicates and carbonaceous material often surrounded by icy mantles, are most probably highly irregular in shape with...
